: Over the past decade, loop-mediated isothermal amplification (LAMP) technology has played an important role in molecular diagnostics. Amongst numerous nucleic acid amplification assays, LAMP stands out in terms of sample-to-answer time, sensitivity, specificity, cost, robustness, and accessibility, making it ideal for field-deployable diagnostics in resource-limited regions.: In this review, we outline the front-end LAMP design practices for point-of-care (POC) applications, including sample handling and various signal readout methodologies. Next, we explore existing LAMP technologies that have been validated with clinical samples in the field. We summarize recent work that utilizes reverse transcription (RT) LAMP to rapidly detect SARS-CoV-2 as an alternative to standard PCR protocols. Finally, we describe challenges in translating LAMP from the benchtop to the field and opportunities for future LAMP assay development and performance reporting.: Despite the popularity of LAMP in the academic research community and a recent surge in interest in LAMP due to the COVID-19 pandemic, there are numerous areas for improvement in the fundamental understanding of LAMP, which are needed to elevate the field of LAMP assay development and characterization.
: 在过去的十年中,环介导等温扩增(LAMP)技术在分子诊断中发挥了重要作用。在众多核酸扩增检测方法中,LAMP 在样本到结果的时间、灵敏度、特异性、成本、稳健性和可及性方面表现出色,非常适合在资源有限的地区进行现场部署诊断。: 在这篇综述中,我们概述了用于即时护理(POC)应用的前端 LAMP 设计实践,包括样本处理和各种信号读取方法。接下来,我们探讨了已经在现场临床样本中得到验证的现有 LAMP 技术。我们总结了最近利用逆转录(RT)LAMP 快速检测 SARS-CoV-2 的工作,作为替代标准 PCR 方案的方法。最后,我们描述了将 LAMP 从实验台转移到现场所面临的挑战,以及未来 LAMP 检测方法开发和性能报告的机会。: 尽管 LAMP 在学术研究界广受欢迎,并且由于 COVID-19 大流行,人们对 LAMP 的兴趣最近也有所增加,但在基本理解 LAMP 方面仍有许多需要改进的地方,这对于提升 LAMP 检测方法的开发和特性研究领域是必要的。
